在实验室内对采自香港的马来栉孔扇贝幼虫进行了人工养殖。幼虫发育包括六个无节幼体阶段和一个非摄食cypris阶段。在121 °C下，仔鱼在20 d内达到鲤形目，而在128 °C下，仔鱼在14 d内达到鲤形目。 利用光学显微镜和扫描电子显微镜对无节幼体和鲤形幼体各阶段的头盾、前角、唇、腹突、触角、触角和下颌骨等形态特征进行了描述和说明。本文试图比较无节幼体和鲤形幼体在形态上的差异。malayensis与其他Chthalus属的种类包括C. stellatus、C.蒙塔吉角dentatus，C. fragilis、脆枝弯角藻C. dalli，C. antennatus，C. fissus和C.挑战者。本文描述了中国对虾的无节幼体。Malayensis与本种以前的描述不一致。
Larvae of Chthamalus malayensis (Cirripedia: Thoracica) from Hong Kong were cultured in the laboratory. Larval development includes six naupliar stages and a non-feeding cypris stage. Larvae reached the cypris stage in 20 d at ∼21°C compared to 14 d at ∼28°C. Morphological features including the cephalic shield, frontal horns, labrum, abdominal process, antennules, antennae and mandibles in all nauplius and cypris stages were described and illustrated using a combination of light microscopy and scanning electron microscopy. Attempts were made to compare morphological differences between the nauplii and cyprid of C. malayensis with those of other Chthamalus species including C. stellatus, C. montagui, C. dentatus, C. fragilis, C. dalli, C. antennatus, C. fissus and C. challengeri. The present description of the nauplii of C. malayensis is not in agreement with the previous description of this species.
